My invention relates'to devices-ally which theremay be held. in definiterelation to one another: such parts of shoesasthose whichwgo to make upthe bottom-portion, theseinel-ud f ing, for: example, a sole-,one-ormorefille-n piece sections, and1a shankreinforcement..

lncertain connections, it maybe-desirable to produce a bottom-unit;including parts of thecharacten indicated 1 above,- this unit f-ha-V fing itselementsso attached that-it:may be securedto the insole and'upper- 'of a shoe by a single operation; the filler:-piece-registeringwith the space over the insolebetween: the inner edgesof the Welt.- Anobject of-this invention is to insure thatthe 'bottom un'it parts orelements tobethus assembled are posi tioned in a series superposedvsuccessively on one another, and so held until theyrhave been securedtoone anotherto form-the un-it. In attaini'ngthisobject, I provide a=noveljor ganization comprising apl-urality of movab le members adapted toboth gage and ho-ld shoe; parts, the particular form ofthe-inventionhereindisclosed beingarran-ged to locate and clamp a -soleWith one section' of a filler pieee, andthen to locat'e'with referencetonsaid sole and filler-piece section another filler-piece sectionandashank-reinforcement, and clamp these, More specifically, I pivot; to "asupportingmember, shown'as -anopen=base frame, as-b'ya spindle rotatablethereon, a plurality of 'work-holdingarms or members, which, as thespindle turns, becomesucces-I sivelyeffective to clamp pieces applied tothe base and to one another.

spaced along the longitudinal axis of the 'frame- These pmsare arrangedto enter cor respondingly spaced openings in such a shoebottom p art asan outsole S, and also=enter rear: "openingand a: depression at the forWard-edge or" a heel filler-piece Fl The en'- gagementwvith the pins ofthe filler-piece sect'ion'floeatesit" With suiticient' accu-racy With Arespect to'thesole upon Which it'rests. But, o-n account ofthelength ofsaid sole, I pre fer-to'provide for the'forepart a vertical gage-surfaceupon amember 20 attached at one side of thebase by aslot and-screwconnection 22;" Tl'iisconnection, giving both an angular -adj ustment"and a movement toward by the gage.

and from the longitudinal axis of the frame, permits the device to beadapted for soles intended for widely different sizes and styles ofshoes. Generally, however, change of this gage member is not necessarywhen contactpoints upon the soles of a line of sizes are so chosen thatthe lie along the line furnished Such points are somewhat at the rear ofthe maximum width of the forepart, where it merges into the oppositecurve of the shank-portion.

From the same side of the base as that at which the gage is fixed risespaced brackets 24, 24, in which is rotatably mounted a spindle 26.Arranged to turn about the forward extremity of the spindle is an arm 28having an angular contact-portion 30, which may be toothed at its lowerextremity to cause it to better retain against displacement from thegage-wall a sole upon which it rests. Secured to the spindle, near thearm 28, is a block 32, and connecting this and the arm is atorsion-spring 34:, which forces the arm yieldably down againstaprojection 36 from the block but permits it to yield circumferentiallyof the spindle. By this arrangement, when the arm is moved by rotationof the spindle into contact with a sole, continued rotation of thespindle is permitted, so that other members which it carries may besuccessively brought into clamping engagement with other bottom-parts.The vertical inner wall of the contact-portion 30 of the arm 28 servesas a gage to position angularly a forer part-filler-piece P when this isapplied to the sole S. The point of engagement between the gage 30 andthe filler-piece section P may, as with the sole, allow the desiredlocating effect transversely of the solefor different sizes. But toprovide for possible extremes, the portion 30 may be adjustable upon aslot-and-screw connection at 38 to the arm 28. The sole S and theheel-filler-piece F ma be placed upon the base together, and positionedin the correct relation to each other by the pins 16 and 18 and the gage20; and to hold the rear extremity of the sole and the heel-filler-pieceagainst the base as the forepart of the sole is clamped by the arm 28,there is carried by the spindle 26, near the end opposite the arm 28, anarm 40. This has a yieldable connection at 4:2 to the spindle, similarto that of the companion arm, and is shown as provided with a dependingendportion 44: in which is an opening registering with the pin 18 duringthe movement of this arm. The lower end of the portion 44 is recessedto. receive the forward edge of the filler-piece F, a surface46 bearingupon the piece to clamp it and a semi-cylindrical wall 48 surounding theforward side of the pin 18 beyond the filler-piece. Against thisperipheral wall 48 is placed a depression in the forepart-filler-pieceP, and a like depression in the shank-reinforcement R. This locates therear extremities of both the elements P and R with reference to thepreviously clamped pieces, both longitudinally and transversely of thesole S. The forward part of the filler-piece P is positioned angularlyby bringing it into engagement with the gage-wall of the portion 80, bywhich the sole is clamped. The exact angular relation of theshank-reinforcement is not important, and its forward end may be locatedtransversely of the filler-piece P, on which it rests, by the'operatorwithout a gage.

The clamping of the piece P and the reinforcement R is preferablyeffected by an arm 50, the separated ends 52, 52 of which bear upon thereinforcement near its opposite extremities. The arm 50 is so mountedupon the spindle between the arms 28 and 40 that it is at a greaterangular distance from the base 10 than are the associated arms whenthese elements are raised to their work-receiving positions. It is alsoarranged to adapt itself to differences in thickness and surfaceinclination of the parts held. For this purpose, the spaced portions 52,52 may be of spring-metal, secured to a block 54:, at the outer side ofwhich is a stem 56 lying substantially at right angles to the spindleand swiveled in a carrier-block 58 fast upon the spindle 26. Theclamping portions 52 therefore not only yield by virtue of theirresilience but also by rocking bodily about the axis of the stem. Aperfect accommodation is therefore obtained, both with reference to eachother and to the companion arms, when pressure is applied to the work.An overhanging portion 59 of the block 58 limits the extent to which theblock 54 may turn. The arm-portions 52 are thus never permitted to swingbeyond a proper work-engaging posrtlon.

The spindle and arms may be turned to produce clamping of the work-partsby a handle 60 fulcrumed upon a head 62 secured to the end of thespindle. From the handle is a projection 64 extending substantiallyparallel to the spindle. This projection cooperates with a series ofteeth 66, 68, formed upon a disk 72 secured to the outer side of theadjacent bracket 24. A spring 7-1, interposed between the handle and thehead 62, exerts its expansive force to press the projection 64: againstthe edge of the dist: 7 2 into co-operation with its teeth. The tooth66, by its contact with the projection 64:, limits the movement of thearms away from the base 10, holding them normally elevated above thebase in positions convenient for the introduction of the parts to beclamped. When the handle and therefore the arms are turned in aclockwise direction, as viewed in F'gs. l to 3 of the drawings, thetooth 68 retains the arms 28 and i0 in the correct positions forclamping the sole S and heeLfillerpiece F; \Vith the-projection inengagement with: the tooth70, the. portions 52,.ofithe arm 54 arelocated .fonclampingtheshank reinforcement and; the; fcrepartefillerepiece P.

. Assuming. that a bottom-unit, made up; of the outside S heel:and;forepartefillerspiece sections F and P, respectively, and shank-reinforcement R, isto be assembled, the de-. vice may be utilized in thefollowingmanner The-handle 60 being raised,;as-isshownin Fig. i of thedrawings, and retainedlby; the frictional engagement ofitsspringrpressed projection with the. disk/Z2, theoperator firstplacesupon the-base-lO theaso-le; and heel? iillerrpiece together, theopenings in theform= er, and the opening and: depression in. the latterreceiving the pins 16*and '18. 'Ihe desiredrelation of the sole:transversely of; the base is insured-by. its contact withthegage 20.3Now the handle-is turnedidown, as illus trated in Fig. 2,- causingthearm 28 toengage andclampthe sole and the arm-4O to'correa spondinglyhold both the sole and heel-filler piece. Yield of the arms at the'irspring-connections 3e and e2to the-spindle allows the pressure to beequalized, and the reaction of the springs also holds theprojections-6ri of thehandleagainst the tooth 68,,thus locking the armsagainst reverse movement. Eel;-

lowingl this, the forepart-iiller+piece section I P and: theshank-reinforcement. E are laid superposed upon. the soleagainst the.gage wail 48 of the arm 40,.which precisely locates these portions withrespect'to the-projection 18, but avoiding contactwith said projection;The other end ofthe -forepart-fillerpiece is gaged by bringing itagainstthe ;,W21ll;Of: the sole-engaging portion 30 of the arm 28. Theposition. ofthe forward endof the'shank; reinforcement across thefiller-.piecewmay be fixed approximately by the operator. Fi: nally',the handle is depressedto bring; the portions 52, 52 of the intermediatearm upon theopposite extremities of. the shank-rein'- forcement, theseadjusting themselves angularly of the worlrby the turning of thestem56.. The resilience of these contactrportions, added-to the force of thespring-connections 34k and 42,,retains the projectionof the ban?dl'e'against the tooth 7.0, all the'arms; being new locked to clamp theentirebottom-unit assembly upon the base w-ithnallthe partsin correct,relation to .one another. the thus-clamped parts, staples maybe driventhrough alll the elements at: any desired points. Freedom frominterference of the clamping device with this operation is assured bythe opening of theframe-lO.

The assembled bottom-unit isthus freedfrom the arms and may be removedfromthebase-pins, leaving thedevice ready for the succeeding opera: tion.
